Production Hardening
The app stays reliable in the wild: crashes are visible, secrets stay put, and offline is a mode, not a failure.

How it works
A left-to-right map of the work. Ports stay on fixed sides so the edges do not cross more than they have to. Pan or pinch if you want a closer look.
- Production app
- Crash + analytics
- Secure tokens
- Network + offline
- Background lifecycle
The usual problem
- Tokens sit in plain storage because “it worked in staging”.
- A flaky network looks like a product bug.
- Field work continues when the radio drops, but the app does not.
How I approach it
- Crash reporting and product analytics are on before the first store build.
- Tokens never sit in plain storage.
- Networking is resilient, and offline-first sync is designed, not patched.
- Background and lifecycle work is part of the architecture.
Process
01
Observe
Crash reporting and analytics from the first production build.
02
Lock down
Secure token storage and a network layer that retries with intent.
03
Survive offline
Sync and background work for the journeys that cannot wait for signal.
04
Handover
What is stored where, and how the app degrades when the network dies.

Proof from real work
What you get
- Crash and analytics wiring
- Secure storage for tokens
- A network and offline strategy the next engineer can follow
How risk stays down
- The app degrades gracefully offline.
- Secrets never sit in plain storage.
